Nic's hack, from the "we do what we must" file:
One thing that I've started doing recently and found really useful is to use the nappy to entertain him on the changing table. We use a combination of disposables and reusables and unfortunately this only works with disposables. Most disposable nappies have little characters drawn on them with big eyes and nice happy smiles. If he's a bit fractious and wriggly, I hold one up in front of his face and he goes all intent and quiet for a moment, long enough to slip the nappy on.
I've found Pampers best for this, but Huggies work well too. There are so many different designs he never seems to get bored. Sometimes I swap nappies to tell stories. It's like a little cartoon for him right there on the mat!
